About thirty people took part in the hands-on lecture. Almost everyone had started learning quantum computing, but only a few people have tried Q#. Few people have used C#, too. Therefore, I focused to learn the first steps to start Q# in this hands-on lecture. This is the material in Japanese and I focused on the first task that day.

According to the feedback collected from participants, they're almost satisfied with this hands-on lecture and we have gotten some feedback on how to improve the hands-on lecture. I share them in this blog.

Instruct step by step to create a project

Since almost everyone is new to .NET Core project, it's good to instruct creating the project by using .NET Core CLI or Visual Studio. I focused on only using Visual Studio Code during this hands-on because it's cross-platform. Actually, some people brought their macOS computers and I used Fedora desktop :). At the beginning of the hands-on lecture, we should instruct on how to create the Q# Console project, run the created project to execute the Q# code. So that everyone can start writing the Q# code.

Instruct C# code

Q# code doesn't run by itself. Q# code is invoked from .NET Core languages such as C#, VB.NET, F#, and PowerShell. So everyone has to learn C# as well as Q#. Since we'd like to focus on learning Q#, we would have to instruct more details about C# code to invoke Q# operation.

Explain the standard library

After the hands-on, I was asked how to write some basic quantum gates such as Rotation, SWAP and so on. Since the Bell State example uses only a few built-in operations such as H,X and M, we should have explained it in this hands-on.

Our Future Plan

Due to the room being at max capacity, we're going to have the same hands-on lecture again in January. We will focus more on Q# code and operations at the event.

According to the feedback, I'd like to continue to hold a hands-on style event for a while. Though it's just an idea, I'll pick up one algorithm example from the Q# sample repository and then instruct it.
